STAAD.Offshore (Version: 03.00.01.02) Installation only
Size: 89 MB
Automatic Wave Load Generation and Design for Offshore and Floating Structures
Overview
STAAD.Offshore is comprised of two primary modules: wave load and transport.
Wave Load Module
The wave load module calculates wave loads on structures using either stream function, Stokes 5th Order theory, AIRY theory, or a user defined grid wave. The program generates STAAD.Pro loading data for the stiffness analysis. The wave load module computes the wave loading intensities due to wave and/or current effects along the submerged portion of the structural members and appurtenances below the wave surface profile, relative to the local X, Y, Z and global X, Y, Z axes. The wave loadings are summed at the joints for each member using simple beam theory from which the total structure base shear and overturning moments are calculated.
The wave can be stepped through the structure in any specified direction over a range subdivided into equal internals using either phase angles or length units. The interval is specified by giving the start and finish positions of the wave crest relative to the structure mud line axis and a step interval.
The wave force co-efficients, drag, and added mass, can be specified independently for each member or using member range. The coefficients are relative to the member local co-ordinate system.
Marine growth and current velocity profiles are specified relative to the mean water level and are described as a discrete set of data points. The magnitude of the current at other elevations is determined by direct interpolation or extrapolation of the data. Alternatively, current flow continuity can be selected. The marine growth is only applied to the members within the profile range that is specified.
The program computes the wave surface profile, wave celerity and wave length. The wave loading intensity along the members is assumed to be linear varying over a segment length. The accuracy is controlled by the user by specifying the appropriate number of segments along the members or by using the auto-segmentation option.
The program generates STAAD.Pro loading data comprising of equivalent simple beam joint loads for buoyancy, wave loading intensities on structural members, and joint loads for wave loading on appurtenances. The structures deadweight can be generated by STAAD.Pro. Other output files include the structure base force summaries. There is an option in the program to neglect the overturning moments at the base that are caused by the vertical forces. This allows the vertical wave force effects to be quantified. The wave forces are calculated from Morison’s equation using either stream functions, Stokes 5th Order, or Airy linear theory, to compute the particle velocities and accelerations, or a user defined grid of velocities and accelerations.
Transport module
The transport module can calculate the inertia forces due to motion accelerations, consisting of any combination of the 3-translational and 3-rotational degrees of freedom. The inertia loads can either be lumped at the nodes, or distributed along the members. The program generates a complete STAAD.Pro input file consisting of basic load cases for the inertia loadings on the structure, together with the STAAD.Pro commands necessary to perform analysis, output displacements, reactions, and member end forces.
Motion loads can be generated in all six degrees of freedom (DOF), and combined, to form basic STAAD.Pro load cases. The DOF motions in a load case can be added or subtracted by specifying a directional load factor, such as -1.2, 1.0 and so on; a factor greater than 1.0 would signify a correction factor being applied to the generated load. If gravity tilt loads are to be generated then the global Y axis must be set vertically upwards. Also, in respect to vessel motions, a suitable axis convention would be to set the global Y axis vertical with the global X axis in the direction of the vessel longitudinal axis.
This convention gives the following correspondence between each DOF in terms of ship motions. Thus, for example, using directional load factors it is possible to form load cases comprising of heave + roll, or heave - roll and heave + pitch, or heave - pitch, to determine the maximum member forces at all positions within a structure.

STAAD.Pro V8i SELECTseries 4 (20.07.09.21) - Trial Version
Size: 450 MB
STAAD.Pro V8i SELECTseries 4 (20.07.09.21)
STAAD.Pro V8i SELECTseries 4 Patch Release:
In August this year, we released SELECTseries 4 of STAAD.Pro V8i. The
main enhancement included in this release was the introduction of the latest
AISC 360-10 steel design code. However, this did not include a few features
that were found to be required by many users that use the AISC code and has led
to production of a new patch release which is now available on the Bentley
SELECT servers. The key issues addressed include:-
1.Deflection Checks,
Enhanced over other AISC deflection checks in that a design will only perform
deflection checks on those load cases classified as SERVICABILITY.
2.Automatic profile selection.
3.Slenderness
Optional checks added with the MAIN and TMAIN parameters
4.Single angle section
Design about both principal and geometric axes.

Waste Management: Research Advances to Convert Waste to Wealth
Author: A. K. Haghi | Size: 6.5 MB | Format:PDF | Quality:Original preprint | Publisher: Nova Science Pub Inc | Year: 2010 | pages: 244 | ISBN: 616684143, 9781616684143
Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is also carried out to recover resources from it. Waste management can involve solid, liquid, gaseous or radioactive substances, with different methods and fields of expertise for each. This book outlines the various options available to meet the twin goals of environmental conservation and sustainable development and brings to light the various ways of converting waste to wealth.

Building Ideas: An Introduction to Architectural Theory
Author: Jonathan A. Hale | Size: 10.9 MB | Format:PDF | Quality:Original preprint | Publisher: John Wiley & Sons | Year: 2000 | pages: 242 | ISBN: 0471851949, 9780471851943
Building Ideas An Introduction to Architectural Theory This book is an essential text for students of architecture and related disciplines, satisfying the demand for an accessible introduction to the major theoretical debates in contemporary architecture. Written in a lucid and user-friendly style, the book also acts as a guide and companion volume to the many primary theoretical texts recently made available in reprinted collections. Whilst architectural monographs, collections of building precedents and polemical manifestoes are growing more and more numerous, Building Ideas is the first book to provide an introduction to such a broad range of issues in architectural theory. This text therefore serves to fill a widening gap between the everyday practice of architecture and the often bewildering field of academic theoretical debate. Beginning with a general introduction to the field of architectural theory, covering the interface between philosophy and technology in the production and interpretation of buildings, the book presents the major theoretical positions in contemporary architecture through a series of thematically structured chapters.
Each chapter deals with a specific approach to the theory and criticism of architecture by presenting a series of related buildings as illustrations of a key theoretical position, as well as setting this position in a cultural and historical context. Under the five broad headings of 'Architecture as Engineering - The Technological Revolution', 'Architecture as Art - Aesthetics in Philosophy', 'The Return of the Body - Phenomenology in Architecture', 'Systems of Communication - Structuralism and Semiotics' and 'Politics and Architecture - The Marxist Tradition', the book presents a wide but critical survey of the central questions in the current theoretical debate. Providing the theoretical tools necessary for an understanding of the history of philosophies and technologies in architecture, this book is essential reading for undergraduate architectural theory courses as well as a first point of reference for anyone wishing to understand the complex connections between architecture and related fields of cultural enquiry.

Dear all,
Im looking the drawing of the raft foundations with bored piles for the above ground liquid storage tanks and also for large machine system.
Thank you in advance.
Solid Waste Management is one of the essential obligatory functions of the Urban Local Bodies/Municipal Corporation. This service is falling too short of the desired level of efficiency and satisfaction resulting in problems of health, sanitation and environmental degradation. Due to lack of serious efforts by town/city authorities, garbage and its management has become a tenacious problem. Moreover, unsafe disposal of garbage and wastewater, coupled with poor hygiene, is creating opportunities for transmission of diseases. Solutions to problems of waste management are available. However, a general lack of awareness of the impact of unattended waste on people’s health and lives, and the widespread perception that the solutions are not affordable have made communities and local authorities apathetic towards the problems. The aim of this Book is to bring together experiences reported from different geographical regions and local contexts. It consolidates the experiences of the experts from different geographical locations viz., Japan, Portugal, Columbia, Greece, India, Brazil, Chile, Australia and others.
